Bleach bath to bleach

I am a natural dark ash blonde.
I have been dying my hair a dark brown for the last few years.
Recently, I let my hair grow for 8 months without dye to see my base color very well.
I went to a stylist and she said she could give me an ash brown color - just a little darker than my natural.
She did a color strip, a bleach bath, and a dye.
She said the dye was an ash color but when applied to my natural ash roots, they became golden.
The length of my hair is lighter than before the process but has a very noticeable red tinted to it. It is also much, much darker than my natural color.
How did ash +ash = golden?
And how can I fix this?
My goal is to be as close to my natural color as possible so I can quit dying all together.
Thank you for your time and any answers.
